(34-43°F) in blood bank refrigerator.
6. How long can blood be out of refrigeration before it must be returned? -
ANSWER 30 minutes maximum before transfusion must begin.
7. What vital signs must be taken before blood transfusion? - ANSWER
Temperature, pulse, respirations, blood pressure, and oxygen saturation.
8. How often should vital signs be monitored during transfusion? -
ANSWER Every 15 minutes for first hour, then every 30 minutes.
9. What is the first sign of a transfusion reaction? - ANSWER Change in
vital signs, especially temperature elevation.
, 10.What should you do if a transfusion reaction is suspected? - ANSWER
Stop transfusion immediately, maintain IV access with normal saline,
notify physician.
Blood Types and Compatibility
11.What blood type is the universal donor? - ANSWER Type O negative (O-
).
12.What blood type is the universal recipient? - ANSWER Type AB positive
(AB+).
13.Can type A blood receive type B blood? - ANSWER No, incompatible
and will cause hemolytic reaction.
14.What happens if incompatible blood is transfused? - ANSWER
Hemolytic reaction, hemolysis, kidney failure, shock, death.
15.What is the Rh factor? - ANSWER Protein on red blood cells; positive if
present, negative if absent.
16.Can Rh negative patient receive Rh positive blood? - ANSWER No, will
develop antibodies and future reactions.
17.What is crossmatching? - ANSWER Testing patient's blood with donor
blood to ensure compatibility.
18.How long is a crossmatch valid? - ANSWER 72 hours from time of
collection.
19.What is type and screen? - ANSWER Determines patient's blood type and
screens for antibodies.
20.What does ABO incompatibility cause? - ANSWER Immediate
hemolytic transfusion reaction.
Transfusion Reactions
21.What are signs of acute hemolytic reaction? - ANSWER Fever, chills,
back pain, chest pain, dyspnea, hypotension.
22.What is febrile non-hemolytic reaction? - ANSWER Fever and chills
without hemolysis, most common reaction.
, 23.How do you treat febrile reaction? - ANSWER Stop transfusion, give
antipyretics, monitor vital signs.
24.What is allergic transfusion reaction? - ANSWER Urticaria, itching, rash
from plasma proteins.
25.How do you treat mild allergic reaction? - ANSWER Give
antihistamines, may continue transfusion if mild.
26.What is anaphylactic reaction? - ANSWER Severe allergic reaction with
bronchospasm, shock, respiratory distress.
27.What is TRALI? - ANSWER Transfusion-Related Acute Lung Injury
causing pulmonary edema.
28.What causes circulatory overload? - ANSWER Transfusing too rapidly or
too much volume.
29.Signs of circulatory overload? - ANSWER Dyspnea, crackles, jugular
vein distention, hypertension.
30.What is delayed hemolytic reaction? - ANSWER Occurs 3-10 days post-
transfusion, gradual hemolysis.
Pre-Transfusion Procedures
31.What must be verified before starting transfusion? - ANSWER Patient
identity, blood type, crossmatch, expiration date.
32.Who must verify blood product information? - ANSWER Two licensed
nurses must double-check all information.
33.What patient identifiers are required? - ANSWER Full name, date of
birth, medical record number, blood bank number.
34.What IV gauge is needed for blood transfusion? - ANSWER 18-20 gauge
catheter minimum for adequate flow.
35.What solution is compatible with blood products? - ANSWER Only
normal saline (0.9% NaCl).
36.Can dextrose solutions be used with blood? - ANSWER No, causes
hemolysis of red blood cells.
